PEDAL ATTACHMENT FOR AUTOMATIC PLAYING DEVICES.

SPECIFICATION forming part of Letters Patent No. 630,557, dated August8, 1899.

Application filed February 4, 1899. Serial No. 704,505. (No model.)

To all whom it may concern.-

Beit known that I, ROBERT W. PAIN, acitizen of the United States,residing in the city of New York, borough of Manhattan, county and Stateof New York, have invented certain new and useful Improvements in thePedal Attachments for Automatic Playing Devices,

of which the following is a specification.

My improvement relates to the pedal attachment of automatic playingdevices such, for example, as the pianola.

I will describe a pedal attachment embodying my improvement and thenpoint out the novel features in the claims.

I11 the accompanying drawings, Figure 1 is a side elevation of a portionof a piano-casing, which is partly in vertical section, and of anautomatic playing device provided with a pedal attachment. Fig. 2 is adetail top View, on an enlarged scale, of a portion of the pedalattachment. Fig. 81s an elevational View, on an enlarged scale, of apedal attachment embodying myinvention. Fig. 4 is a detail elevationalview, 011 an enlarged scale, of a portion of the pedal attachment.

Similar letters of reference refer to corresponding parts throughout thefigures.

A represents a portion of a piano, a one of the pedals thereof, and B anautomatic playing device-for example, a pianola-having a pedalattachment. This attachment, as is usual in this class of devices, isoperated by a lever (not shown) within reach of an operator. This leveroperates a shaft 12, carrying an arm I), which gives longitudinalmovement to a vertical rod or shaft 0*, carrying the pedal. A guide bcarried by the casing b of the pianola, is provided for the end of theshaft b O represents the pedal, having a collar 0, which is loose uponthe shaft 11 The collar 0 of the pedal is normally held against a collarc by means of a spring 0 The collar 0 is adjustable on the shaft b bymeans of a set-screw c and the adjustment of this collar permits of theadjustment of the pedal according to the height of the piano-pedal a. 0represents a flange or rim on the collar 0', and c a recess or openingin said flange, in which a pin 0 on the collar 0 fits. The purpose ofthis arrangement is to prevent rotary movement of the pedal when inoperative position. \Vhen the pedal is to be moved out of operativeposition, it is moved vertically against the action of the spring androtated on the shaft until it is in a position similar to that shown bydotted lines in Fig. 2. If desired, a second recess or opening maybeprovided in the flange o with which the pin may be engaged when thepedal is out of operative position.

0 represents an adjustable collar on the shaft b for limiting thevertical movement of the pedal when it is to be moved out of engagementwith the flange or rim 0.

\Vhat I claim as my invention is- 1. The combination of al0ngitudinallymovable rod or shaft, an adjustable collar on said shaft,a pedal carried by said shaft and adapted to be moved vertically thereonindependently thereof, and means forholding said pedal in engagementwith said collar.

2. The combination of a longitudinallymovable rod or shaft, anadjustable collar on said shaft, a pedal carried by said shaft so as tohave vertical and rotary movement thereon, and a spring for holding saidpedal in engagement with said collar.

The combination of a longitudinallymovable rod or shaft, an adjustablecollar on said shaft, a rim or flange on said collar provided with anopening or recess, a pedal carried by said shaft so asto have verticaland rotary movement thereon, a pin on said pedal adapted to lit in saidrecess or opening, and a spring for holding said pin in said recess,substantially as described.

4. The combination of a longitudinallymovable rod or shaft, a collar'onsaid shaft, a pedal carried by said shaft, so as to have vertical androtary movement thereon and adapted to be locked with said collar, andmeans for limiting the vertical movement of said pedal on the rod orshaft;

5. The combination of a longitudinally movable rod or shaft, a pedalcarried by said shaft and adapted to have vertical and rotary movementindependently of the shaft, a collar carried by said shaft with whichthe pedal engages to prevent its rotary movement, and a second collarcarried by said shaft for limiting the vertical movement of the pedal.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

I ROBERT W. PAIN.
